Lesson details
Key learning points
- To find the area of a rectangle you multiply the length by the width.
- Compare different methods to decompose shapes and decide which is the most efficient.
- Choose the most efficient calculation strategies to calculate the area of a compound rectilinear shape.
Common misconception
Pupils may think that there is only one possible answer to some problems or only one way to solve a problem.
Discuss whether there is only one possible answer to a problem or if there are many solutions. Ensure that more than one approach to solving a problem is modelled where appropriate.
Keywords
Dimension - A dimension is a measure of length in one direction.
